Giuliani: Charlie Crist Is the Person I Least Respect

Former New York City Mayor Rudy Giuliani says former Florida Gov. Charlie Crist is the person in politics for whom he has the least respect.

Appearing at a campaign event in Miami on Wednesday for Crist's Republican opponent, current Gov. Rick Scott, Giuliani listed his years in politics, dating back to the Reagan administration.

"I have met a lot of people in politics," some good, some OK, and some I didn't like, Giuliani said. "I've never met a person in politics that I disrespect more than Charlie Crist."

Crist was a Republican when he served as governor of the Sunshine State from 2007 to 2011. He opted not to seek a second term, instead running for U.S. Senate. When he began losing in the polls to eventual winner Marco Rubio, he ran as an independent.

After endorsing Democratic President Barack Obama in 2012, Crist officially became a Democrat and now is fighting to get his old job back.

The party switch has brought accusations of political opportunism, but The Washington Free Beacon reports that Giuliani's disrespect for Crist goes back to the 2008 presidential campaign, when Crist purportedly promised to endorse Giuliani in the primaries but endorsed Arizona Sen. John McCain instead.
